3.7V 1S 5V to 27V Output DC Step-Up Converter and Charger Combi Module

This product is an adjustable boost converter combined with charging module.

Battery: Li-ion 3.7V 1S (not included with this kit)

Boost Converter Function:
Output Voltage: 4.3 to 27V adjustable
Output Power: 7W

Charging Function:
Charging Cut-off Voltage: 4.2V
Charging Current: 1A max


Notes:

1. Default output voltage as sold is unknown. Make sure to adjust it to the desired output voltage before using.

2. Output current is limited by the 7W power rating. At 5V output, the current is limited to about 1.4A. This current capability is reduced as the output voltage is raised by roughly I = 7/Vout.
